So on Mastadon do you see Lemmy posts as the Mastadon equivalent of a Tweet?
I never see posts and comments from Mastadon users on Lemmy even though I believe it’s more popular so you would expect there to be more or at least a similar number as from Lemmy users. I think your comment is only the second I’ve seen from Mastadon users.
Like the other reply says, the user tag of the last Mastadon user I saw was [name]@null, though yours is fine for me now. Also odd that your attached images don’t show even though Lemmy has that feature too. Maybe these issues will be ironed out soon
